Renewed April 8, 1938 29 Claims.

This invention relates to container cover applying machines, and has for its principal object to provide a machine for applying the container cover disclosed in the patent of Frank O'Neill, Jr., No.1,828,906 issued October 2'7, 1931, according to the method also disclosed therein. The disclosure of that patent, therefore, is hereby incorporated into this application.

Other objects and featu'res of novelty will be apparent as the following description proceeds, reference being had to the accompanying drawings, in which Figure 1 is avertical axial section through the head of the container cover applying machine according to the preferred embodiment of the present invention; 7 Figure 2 is a radial section through a container with a cover being applied thereto, taken along the line 2-2 of Figure 1;

Figure 11 shows the roll completed, and

Figure 12 shows the roll flattened.

Referring'more specifically to the drawings the improved cap blank is shown in Figures 1, 2 and .3 as, comprising'a central body portion I adapted .to overlie the mouth of a bottle or other container, radial, substantially T-shaped fingers 2, 3, 4 and 5 and intervening radial tabs 6, l, 8 and 9. In applying-the'cap to a bottle the central body portion l is placed over the mouth of a bottle and in contact therewith. The tabs 6, l, '8 and 9 are then bent downwardly over the bottle lip. Next the fingers 2, 3, 4 and 5 are bent downwardly over the'bottle lip overlying the tabs .5, l, 8 and 9. The adjacent lateral ends of the fingers 2-3, 34, 45, and 52 are then secured together in a manner hereinafter to be described, therebycausing the fingers to constitute a con- ,stricted band gripping the bottle neck below the lip thereof, as shown inFig. 1, to preclude removal of the cap without destruction thereof.

To facilitate feeding the cap blank into a position overlying the bottle mouth, each blank is preferably formed with one or more apertures 5 which are successively entered by a suitable projection on the feeding mechanism of the bottle capping machine, not shown. This insures positive feeding of the cap-blank ribbon and the accurate positioning of each blank relative to the bottle upon which it is to be secured.

The cap blank is preferably made of paper and after certain printed matter has been applied thereto the blank is treated with a waterproof coating. The central body portion of the blank 5 and selected ones or all of the tabs and fingers will, in use, usually be provided with suitable advertising matter.

This invention provides a new means for securing together complemental portions of the cap blank to cause the completed and applied cap tightly to be secured upon the bottle and to preclude removal of the cap without destruction thereof. To this end, the fingers 2, 3, 4 and 5 are provided, at their outer ends, with lateral extensions the combined length of which is greater than the circumference of the bottle neck. The adjacent ends of these extensions are adapted to be interlocked to form a continuous band about the bottle neck beneath the lip thereof. Prefer- O ably, but not necessarily, the lateral extensions of two of said fingers will be of soft metal or similar material which will retain any given shape. This'may be accomplished by securing to the radial fingers 2 and 4 soft metal strips s. b Thesev strips are preferably attached to the fingers by tangs punched from said strips and projected through the fingers and turned back on the underside thereof. The strips s are longer than the width of the head of the fingers 2 and 4V 40 and project beyond the sides of the heads as shown in Figs. 2 and 11.

The cap blanks preferably are fed into a suitable automatic capping machine in ribbon form the finger 5 of each blank being formed integral with the finger 3 of a succeeding blank. Upon arrival at capping position each blank is severed from the ribbon and attached to a bottle.

The container cover applying machine according to the present invention comprises generally an operating head, which can be used in either a line delivery machine or in a rotary machine, although in the drawings we have shown it as originally applied to a line delivery machine.

The frame of the head comprises generally an upper cylindrical plunger barrel l0, and a lower flat curling table l2. Telescoping plungers I3, |4, l5, and I6 are slidably mounted in the barrel I Ill, and respectively carry folding fingers, or parts gether, the metal clip and the paper strips which form the sealing band about the container neck. These slides are operated by rollers following in cam tracks in a cam plate 2| rotatably mounted above the curling table l2, and driven by a gear 22 meshing with a pinion 23 keyed on the shaft of wheel 24 driven by a worm 25 from the source of power for the machine.

The machine therefore comprises broadly a folding finger mechanism and a curling mechanism. The folding finger mechanism positions the blank and folds it to bring the parts into position to be operated upon by the curling mechanism, and hold them in that position. The curling mechanism cooperates with the folding finger mechanism to complete the operation, by rolling the metal and paper ends together to form the constricted band about the container neck.

Folding finger mechanism The cover clamping plunger I3 comprises a flat head, and a stem slidable in a bore in the diagonal finger plunger I4, being urged outwardly by a coil compression spring 26. This stem is re tained by a pin 21 extending through the plunger I4, and working in a slot in the plunger I3.

The diagonal tab finger plunger l4 has a cupped head provided with four depending integral short fingers. The stem of this plunger is the longest, and it extends up out of the barrel Ill, being made in two threaded parts for easy assembly. The upper part passes through the end of an operating lever 30.

The diameter flap finger plunger l5 has a generally flat head, slotted to pivotally receive four long fingers 32. These are spring pressed outwardly and the stem of this plunger is of intermediate length, and it is urged downwardly by a coil compression spring 33.

The head of the outer plunger I6 is cupped and radially flanged, this flange and the head of plunger l5 being held in alignment by a vertical pin 35 passing through both. This flange is cushioned by coil compression spring 36 in recess in the bottom flange of the barrel Hi. This flange cooperates with operating lugs 3'! on. the fingers 32.

Operation of folding finger mechanism The flat paper caps with the metal clips preformed thereon are supplied to the container cover applying machine by suitable feeding mechanism preferably comprising a reciprocating finger on a slide, the individual blanks being severed from a roll or strip after the initial feeding movement. The container or bottle as shown by the dotted lines, is in the position shown in Figure 3, with a container cover blank in position thereabove as shown by the dotted lines, having been located by the feeding mechanism just referred to. The usual bottle elevating mechanism now raises the bottle, which raises the plunger [3 with the blank therebetween, against the action of the spring 26. This movement brings the cover blank against the four short fingers on the head of the plunger M, which fold down the short diagonal tabs of the cover blank.

Further upward movement of the bottle or container causes the head of plunger l3 to engage the head of plunger I4, so that the two move bodily upward as a unit. This movement causes the diameter flap folding fingers 32 to engage the diameter tabs and fold the diameter tabs downward.

Further upward movement of the bottle causes the head of plunger M to abut the head of plunger I5 and the three now move upward as a unit. When the operating lugs 37 engage the flange of plunger It, the fingers 32 are cammed inwardly thereby, to bringthe diameter tabs into snug engagement with the neck of the bottle.

Curling mechanism Mounted in the guide I! of the curling table |2 as shown in Figure '7, is a slide 40 which carries the mechanism for engaging the metal clips S, conforming the central portion thereof to the container neck,,and rolling up the preformed ends S thereof. An identical slide is mounted in the opposite guide IS, with identical mechanism for performing the same operations on the other side of the container neck.

The slide 40 has heels 1!] which abut the guide IT to limit the total inward movement of this slide 40. A wide central longitudinal groove is formed in the upper side of the slide 40, and this groove is flared at its inner end, so as to receive a Y-p-late 4|. The Y-plate 4| is normally retracted to hold its fork against the flared end of the groove in the slide 40, by coil compression springs 42 which are interposed between abutments on the slide 40 and the heel of the Y-plate 4|.

Deeper angularly disposed grooves are also formed in the inner end portion of the slide 40, and slidably receive curling bars 44, which are notched or halved together in crossing relation, with clearances for simultaneous movement. The rear ends of these curling bars 44 are also notched to respectively receive the branches or forks of the Y-plate 4|. l

Pivoted on the under side of the slide 49, are a pair of clip locating fingers 45. These fingers 45 are notched or halved together in crossing relation. The front ends of these fingers are of thickness sufficient to bring their tops flush with the bars 44 and the Y-plate 4|. Springs 41 mounted in bores in the slide 40, respectively urge the fingers 45 into their position shown in Figure 7.

The Y-plate 4| carries a roller 43 which follows in an intermediate cam track 49 in the cam disk 2|.

Displaced 90 degrees from the guide H is the guide l8 in which is mounted a slide 52, which carries the mechanism for conforming the central portion of the paper strip to the neck of the container, and for coordinating the ends t thereof with the ends S of the metal clip. An identical slide is mounted in the opposite guide 251, with identical mechanism for performing the same operations on the other side of the container neck.

The slide 52 has shoulders 1| operating in recesses in the guide l8, which abut the inner ends of the recesses to limit the inward movement of the slide 52. A Y-plate 53 is slidably mounted in a central groove in the slide 52, the inner end of the groove being flared to receive the fork thereof. The front end of the slide 52 has deep crossed grooves therein, in which are slidably mounted paper spreading bars 54. These bars lows an outer track 51 in the cam plate 2|.

are notched or halved together with clearance for simultaneous movement tangential to the container neck. Spring pressed rods 55 enter bores in the butts of these bars 54 and urge them tangentially toward the container.

1 The Y-plate 53 carries a roller 56 which fol- As shown in Figure 4, this track has a spring pressed pad 61' at a predetermined point therealong, for a purpose which will hereinafter appear;

The slide 52 carries a roller 60, which follows an inner track 62 in the same cam plate 2|. As shown in Figure 5, a spring pressed pad 66 is mounted at a predetermined point along the track 62, for a purpose hereinafter described.

Operation of curling mechanism After the container cover blank has been folded down as described in the operation of the finger folding mechanism, the curling mecha- V nism operates to coordinate the metal clip and 22-, drives the cam plate 2|.

the roller 48 inward, causing the Y-plate 4| cushions this movement.

the paper strip and roll them up together. The cover is already on top of the container mouth, and is held by the long folding fingers 32, which hold the diameter flaps against the neck of the container. i

The power of the machine is applied to the worm 25, whichthrough the gearing 24, 23 and The track 49 cams and the slide 40 to move inward bodily as a unit. This causes the clip locating fingers 45 to engage the metal clip and form it to the container neck. In this operation the fingers 45 spread until they snugly enter the preformed angle of the metal clip, as shown in'Figu're 9.

The track 62 now causes the roller 60 to move the slide 52 inward, causing the concave face 59 at the inner end of the slide 52, to engage the paper strip, and conform the same snugly to the neck of the container. Then the spring pressed pad 61in track 51 cams the roller 56 inwardly, forcing the Y-plate 53 to slide inwardly on the slide 52. This movement of the Y-plate, by the forks thereof engaging notches in the crossing fingers 54, cams these fingers 54 tangentially with respect to the container neck until the ends of fingers 54 abut the ends of fingers 44, as shown in Figure 10. The spring mounting of the pad 61 By this movement of the fingers 54, the ends t of the paper strip are wiped against the turned back ends S of the metal clip, which are being held by the clip spreading fingers 45. This brings the parts to the position shown in Figure 10.

The next step involvesfurther action with respect to the slide 40.

The track 49 cams the roller 48 further inwardly, causing the Y-plate 4| to move inward with respect to the slide 40, which. is at the limit of its inward movement, because the heels thereof engage the outer end of the guide This further inward movement of the Y-plate 4| causes the forks thereof to cam the curling bars 44 tangentially to the container neck. In this movement, the bars 44 slide along the adjacent faces of the clip holding fingers 45.

The curling bars 44 have curling dies 65 in the inner ends thereof, constituted by concave recesses or cylindrical depressions. Hence the forward movement of the bars 44 cause the dies 65 to engage the preformed (curl) ends 1' and start to roll them up, as shown in Figure 10.

It should be noted that during the tangential ;movement of the dies 65, the ends of the bars 44 abut the ends of the bars 54. As to the bars 44 are positively driven (roller 48) and the bars 54 are merely resiliently pressed (spring plungers 55) the ends of bars 54 exert a back pressure which is overcome, but always maintains pressure between the ends of fingers 54 and 44.

As the bars 44 slide along the fingers 45, the paper strip t which is held onto the metal strip end S, is rolled up therewith, as shown in Figure 11, forming the roll :17.

The track 62 now camsthe roller 60 outward, which moves the plate 52 back bodily a distance slightly larger than the diameter of roll .1. As the spring plungers 55 are bearing on the bars 54, the abutment with the fingers 44 is maintained, but the fingers are out of alignment a distance greater than the diameter of the roll :13.

The track 49 now cams the roller 48, to move the Y-plate 4| outward, which results in retracting the bars 44 for a distance sufficient to permit the spring plungers 55 to project the fingers 54 to a position over and beyond the rolls :1:, as shown in Figure 12.

The track 62 contains a spring pressed pad 66, which strikes the roller 60, and drives it inward, carrying the slide 52 and the bars 54 therein as a unit. Thus a sort of hammer blow is given to the bars 54 overlapping the rolls x, which flattens these rolls as shown in Figure 12. The spring mounting of the pad 66 allows for variation in the size of containers, and avoids breakage of bottles. The surface of the bars 54 at the points of contact with the roll a: may be depressed, or engraved, so as to give any desired shape to the flattened roll, or to impress a character or seal thereon.

Of course, as the mechanisms in the guides l9 and 2|! are respectively identical with those in the opposite guides I! and I8, and as the cam tracks 49, 51. and 62 are continued and repeated for the other half of the cam plate, the operations just described are duplicated simultaneously on the other side of the container neck.

It should be noted that a ninety degree movement of the cam plate 2| completes the operation, and the next ninety degree movement is employed for return movement, so that a com plete cycle of operations takes place in a 180 degree movement of the cam plate. Hence two successive covers can be applied by one revolution of the cam plate 2|.

While the drawings show the curling or crimping or sealing members as sliding on the curling table, it is tobe understood that these curling members may be otherwise mounted, so as to otherwise move in for their functions, instead of sliding in, as shown. The movements in this event are cam actuated by the vertical movement of the bottle, thus eliminating the power drive 2'4, 25, etc. Furthermore, these modifications may be designed to permit a more compact head, allowing the heads to be more closely spaced as is desirable with a rotary type of bottle conveying mechanism.

Our invention embraces such embodiments of the broad idea as fall within the scope of the appended claims.
